# buildout.autoextras

Buildout (zc.buildout) extension for including setuptools extras_require options for all items in a target option if the extra exists.

## Usage

This is a buildout extension, so simply add it to your extensions list:

[buildout]
extensions = buildout.autoextras


## Options

There are two options...

autoextra-keys
A list of extra keys (e.g. test, zcml, etc.) that should be included if the package has the extra.
autoextra-targets
A list of targets to check for the extras. For example, a buildout part named demo that has an eggs option. The target in this case would be demo:eggs. This is similar to zc.buildout's variable replace syntax except without the \${} symbolling.

Together these options might look something like:

[buildout]
extensions = buildout.autoextras
parts = demo
autoextra-keys = zcml
autoextra-targets = demo:eggs

[demo]
recipe = zc.recipe.eggs
eggs =
zope.testing
zope.i18n
